where r is the radius and C is the circumference. The
TE
equation solved for r is r =
27
O r=4
O r= 8
O r= 12
O r= 16

Answer:

The circumference of a circle is equal to π , which is a number ≈3.14 , multiplied by the diameter of the circle. Therefore ... We also know that the diameter has twice the length of the radius. In equation form: 2r=d. 2r=16. r=8. Note that since 2r=d , the equation C=2πr holds and can be used in place of C=πd .
